Description

Detachable sandpaper lock clamp structure

The present invention relates to a detachable sandpaper leveling tool, in particular to a construction technician who is convenient for construction workers to work on the wood board.

Press, in general, when decorating paints and paintings, it is often affected by the unevenness of the surface of the wooden wallboard, which affects the aesthetics of the paint wall. Therefore, after the basement is carried out on the wooden wall and the soil is filled in the recess, Then use sandpaper to grind the surface in the soil and then paint.

When the painter is used for sandpaper sanding, a sandpaper lock clamp is used. For example, the tool disclosed in the national sandpaper leveling tool No. 103205331 is provided with four elastics on the top surface of the bottom plate. The clamp must be clamped to the four elastic clips provided by the conventional sandpaper lock clamp, so that the wall surface smoothing operation can be performed.

However, the conventional sandpaper locking clamp has to open the four elastic clips in sequence, and then the four corners of the sandpaper are clamped one by one in the four elastic clips, which is quite inconvenient to use and affects the smoothing operation. effectiveness.

In view of the problem of the conventional sandpaper lock clamp, the creator of the present invention has created a detachable sandpaper lock clamp structure, the main purpose of which is to provide a detachable sandpaper lock clamp which can improve the efficiency of the smoothing operation. Structure; the secondary purpose of the present invention is to provide a detachable sandpaper lock clamp structure that is easy to assemble and manufacture.

The detachable sandpaper locking clamp structure of the present invention achieves the above purpose, and adopts the following technical means, which comprises: a clamping and fixing layer, which is made of a hard property and provided with at least one perforation, and the clamping is fixed The laminate provides the function of clamping and fixing the sandpaper; a main body panel is located below the clamping and fixing laminate, and at least one screw hole is provided for the perforation corresponding to the fixed laminate; a sponge cushion is bonded The bottom of the main body plate; and a handle further includes a grip portion, and a pressing surface is disposed at a bottom of the grip portion, and the pressing surface has a coupling screw extending downwardly, and the coupling screw is worn. After the clamping and fixing layer is stretched, the pressing surface is pressed against the clamping fixing layer in the screw hole of the main body board.

The main body plate is formed in two parts and is composed of a hard layer and a soft layer, that is, the hard layer is bonded to the top surface of the soft layer.

The main body plate is integrally formed and has a hard surface and a soft surface.

The area of the pressing surface of the handle is larger than the cross-sectional area of the coupling screw.

The grip portion of the handle is provided with a curved shape.

The above-mentioned detachable sandpaper lock clamp structure is made of wood, plastic or metal material.

The clamping fixed layer plate and the main body plate may hold any opposite two side ends of the sandpaper.

The detachable sandpaper lock clamp structure of the present invention can achieve the following effects by the above technical means:

1. The novel structure can be easily installed and clamped with sandpaper, and the hardness of each layer of the plate is gradually softened from top to bottom, and the grip is curved, which is easy to apply force, so that the sand can be enhanced. The feel of the grinding makes the hand not easy to fatigue, and the sandpaper is easily clamped and not easy to fall off, thereby improving the efficiency of the sanding operation.

2. The novel structure is assembled by stacking layers, which is easy to assemble and manufacture, so the manufacturing cost is low; further, the hard layer (or hard surface) and the soft layer (or soft surface) of the main body panel are sanded by visible wall surface. The types of work are interchanged. For example, in a heavy sanding operation, the hard layer is on the bottom and the soft layer is on the top, and the light sanding operation is reversed.

First, referring to FIG. 1 to FIG. 3, the present invention relates to a detachable sandpaper locking clamp structure A, which comprises: a clamping fixed layer 1, a main body board 2, and a sponge cushion layer 3. And a handle 4; wherein the clamping and fixing layer 1 is made of a hard nature and is provided with a through hole 11, and the through hole 11 may be a single one (as shown in FIG. 1) or a plurality of arrangements (as shown in FIG. 5), and The clamping and fixing layer 1 provides the function of clamping and fixing a sandpaper 5; and the clamping and fixing layer 1 can be made of hard wood, plastic or metal; the main body board 2 is located in the folder Holding the bottom of the fixed layer 1 and corresponding to the through hole 11 of the fixed layer 1 , a screw hole 20 is provided, and the screw hole corresponding to the hole 11 can be a single one (as shown in FIG. 2 ) or a plurality of rows. Column (as shown in FIG. 5); in particular, the main body panel 2 can be integrated (as shown in FIG. 2) or two-piece (as shown in FIG. 2a). If the main body panel 2 is integrated, the main panel 2 Having a hard surface and a soft surface, the hard surface is matched with the clamping and fixing layer 1 to jointly hold the sandpaper 5; if the main body panel 2 is two-piece, the main body 2 is made of a hard layer 21 and a soft layer 22, that is, the hard layer 21 is adhered to the top surface of the soft layer 22, and the hard layer 21 is fitted to the clamping and fixing layer 1 to jointly hold the sandpaper 5; further, the hard layer 21 can be made of hard wood, plastic or metal, and the soft layer 22 can be made of soft wood, plastic, etc.; the sponge pad 3 is bonded to the body. The bottom of the plate 2; and the handle 4 further includes a holding portion 41, and a pressing surface 411 is disposed at the bottom of the holding portion 41, and the pressing surface 411 has a coupling screw 42 extending downward. After the bonding screw 42 extends through the clamping and fixing layer 1 , the pressing surface 411 is pressed against the clamping hole 610 in the main body plate 2 . 1 top surface; further, the grip 4 can be made of a hard material such as wood, plastic or metal; further, the area of the pressing surface 411 of the handle 4 is larger than the cross-sectional area of the coupling screw 42. The pressing surface 411 is pressed against the clamping fixing layer 1 by a profit; the grip portion 41 of the handle 4 is provided with a curved shape for convenient use by a person, as shown in FIG.

Referring to FIG. 4 , the detachable sandpaper locking clamp structure A of the present invention is used to extend the coupling screw 42 of the handle 4 to the through hole 11 of the clamping fixing layer 1 and then combined with The screw hole 20 of the main body board 2 is then bent into a shape of a sandpaper, and then any two opposite side ends 51 of the four sides of the sandpaper 5 are respectively clamped to the clamping fixed layer board 1 and the main body board. Between 2, as shown in FIG. 2 and FIG. 2a, finally, the handle 4 is locked, and the pressing surface 411 is pressed tightly against the clamping fixing layer 1 so that the clamping layer 1 and the main body are fixed. The sandpaper 5 is pressed tightly between the plates 2. Finally, the user can hold the sandpaper lock clamp structure A and reciprocally sand the wall surface 6.

In summary, the present invention relates to a "removable sandpaper lock clamp structure", and the hardness of each layer of the plate is gradually softened from top to bottom, and the grip is curved. The shape is easy to apply force, which can improve the feel of sanding, make the hand not easy to fatigue, and the sandpaper is easy to be clamped and not easy to fall off, thereby improving the efficiency of the sanding operation; and the novel structure is superposed by layers The combination is easy to assemble and manufacture, so the manufacturing cost is low; in addition, the hard layer and the soft layer of the main body panel can be interchanged according to the type of sanding operation of the wall surface. For example, in the heavy sanding operation, the hard layer is on the lower layer and the soft layer is on the upper layer. Light sanding operations are the opposite.
